19 Claims.

The present invention relates to spindles, and particularly mountings or journals for spindles of spinning and twisting machines. This application is a continuation in part of our joint application for Spindles and mountings or journals therefor, S. N. 114,997, led December 9, 1937.

Patent No. 1,511,257, issued to Herbert G. Beede, one of the joint inventors herein, on October 14, 1924 shows the blade of the spindle driven by the usual driving band, and the blade so mounted as to obtain a cushioned lateral movement of the lower portion thereof, to permit alignment or centering of the center of gravity with the axis of rotation of the spindle blade. Spindles and mountings therefor made in accordance with said patent have been used successfully for bobbins of relatively small sizes such as had large bobbin at greatly increased speed and at ordinary speed with true vertical alignment or centering of the center of gravity of the axis of the spindle blade with a bobbin mounted thereon, so as to prevent a hammering effect between the bobbin and the blade as well as between the blade and the mounting or journals.

In actual practice we have found that the object above stated can be and is accomplished by providing a mounting or journal capable of absorbing substantialy all vibrations, which vibrations vary with the speed of rotationv and the unbalancing of the rotating spindle blade with balanced or unbalanced loaded bobbin. In other words the varying conditions to which the spindle blade is subjected, either because of `varying speeds orvarying load, or both, result in the creation of a series of vibrations, (primary, secondary, tertiary) which must be substantially absorbed to obtain a smoothly operating spindle.

The ever increasing load or weight on the bobbins, especially at high speed and with large bobbins, causes a gyratory or oscillating action which naturally results in hammering of the bobbins on the blades as well as on the journals which re? ioning is lacking. Thevspindle and mountings r therefor shown and described in the accompanying drawings, under actual tests has been found to function perfectly over a long period of time and to meet all .of theconditions mentioned above. The reasons will be' hereinafter pointed out in detail.

A further object of our invention is to eliminate the pumping orsplashing of oil which has occurred in former types of bolsters. We have found that if the upper portions of the respective bolster means are so closely spaced at a proper clearance distance from each other or from the bolster case for a substantial distance adjacent the upper end thereof that a continuous film of lubricant will be urged upwards by the vibration of the spindle blade to continuously ooze inwardly over the upper end of the respective bolster means to lubricate the bearing and spindle blade, and thus by selecting the proper clearance between the respective upper ends of the bolster means and outer bolster means and bolster case we are able to substantially eliminate all objectionable forms of splashing present in other types of spindles.

We have also discovered that if the respective bolster means are so closely spaced from each other and the outermost bolster means from the bolster case substantially throughout the height thereof, that a continuous upward flow of lubricant will be urged upwardly by the capillary action of the lubricant itself without any rotation of the spindle blade, but that a capillary lm will form adjacent the upper end of the bolster case. We have supplementally discovered, however, that the surface tension of this lm may be broken vby the high speed rotationv of the spindle blade thereby permitting the oil to be forced to continuously ooze inwardly over the upper ends of the respective bolster means and downwardly to the lower bearing hole to lubricate the bearings and spindle. Thus by establishing the proper clearance, this continuous upward circulation of lubricant will be provided on rotation of the spindle blade.

' Before proceeding with a detailed description of the embodiments of the invention illustrated in the accompanying drawings, we would point that the invention applies not only to spindles and mountings therefor embodying antifriction bearings of the type disclosed in the said Patent #1,511,257 in which the bearing is near the pivot of oscillation, but to spindles and mountings of the plain bearing type, as well as spindles and mountings using antifriction bearings regardless `taken on the line 2-2 of Fig. 1, with a portion of the bobbin and parts surrounding theblade broken away; Fig. 3 is a view similar to Fig. 2 showing modification of the invention; and

Figs. 4 and 5 are views similar to Figs. 2 and 3 showing further modifications of the invention Fig. 6 is an enlarged vertical sectional view similar to Fig. 2 showing a modification of the invention with the plug removed to permit initial axial ow out the lower end of the bearing hole prior to its radial circulation outwards.

Fig. '7 is a cross sectional view taken along the line 'I--l of Fig. 6.

Fig. 8 is a cross sectional view taken along the line 8-8 of Fig. 6.

Fig. 9 is a cross sectional view taken along the line 9-9 of Fig. 6.

In the drawings, the letter B designates generally the bobbin having end flanges, 8, between which the thread is spun or twisted during a relatively long traverse. The illustrated bobbin, as previously mentioned, is of suflicient size to contain at least a pound of thread, or yarn. The

numeral 'I designates generally a bolster-case lubricating oil, a radial clearance of about adapted' to be secured to the usual rail R by means of the lock nut 8 to hold the bolster-case securely in proper position. A bolster 9, extends substantially to the top of the bolster case 1 and is loosely fitted in the bolster-case so as to have a floating action. A ball bearing, I0, is shown arranged within the upper end of the bolster, 9. Blade II, of the spindle is keyed orfastened to the inner race of the ball bearing, and is driven by the whirl I2, which also receives and drives the bobbin, B.

The lower end of the blade II, is pointed as indicated by the numeral I3, and rests on the surface I4, of a wear resisting plug I5, held within the step I6, by pin I1, which also connects step I6, to the inner bolster I8. The lower end of the blade II is loosely contained within a central hole I5a within the step I 6. 'I'hus the load is supported by the inner bolster I8, and relative rotation between the bolsters, 9 and I8,

' is prevented by pin or keyY I9, located adjacent the top of the inner bolster I8. It will be noted that the inner bolster extends a substantial distance upwardly Within the outer bolster 9, and is arranged concentrically therewith and in slight spaced relation thereto. The purpose of these constructions will be presently pointed out in connection with the operation of the spindle.

Since the inner bolster I9 carries step I8 receiving the reduced lower end of blade I I, and plug I5, which forms the bearing for the lower end of the blade I I, and is loosely fitted within bolster 9, several relative movements are possible to absorb all vibrations. For instance, the bolster I8 may move laterally relative to the bolster 9, the bolster 9 relative to casing 1, and blade II relative to bolster I8. It should be noted that the pin I9, is arranged within a relatively large opening 20 facilitating relative movements between the holsters.

In the construction of Fig. 2, as shown and described, the load is supported on the lower end of the blade and by bolster I8, but the spindle may be supported on the ball bearing as in the case of the said Patent 1,511,257, without departing from the essential and novel features of the present invention.

As previously mentioned the inner bolster I8 is loosely mounted within the bolster 9, which is also loosely mounted within the case 1. Thus oil or other lubricant supplied to the interior of the case forms illms between the case and bolster 9, as well as between the bolster I8 and bolster 9, and around the lower portion of blade I I. In order for an oil illm to be formed between the case I and the outer bolster 9 capable of being continuously urged upwards by the rotation of the spindle blade, the outer bolster 9 must be closely spaced from the bolster case for a substantial distance adjacent the upper end thereof. The exact clearance distance depends somewhat on the nature and vicosity of the lubricant employed. With standard types of light .002 inch has been sufcient to provide the creation of a continuous upwardly traveling oil lm between the outer bolster 9 and case 'I on rotation of the spindle blade. In the prior art this result has not been attained for this clearance has been much greater, size for size of spindle blade. On the other hand, the clearance must not be too small to prevent the formation of oil globules to make up the illm. With the proper clearance between the outer bolster 9 and the bolster case 'I for a substantial distance adjacent the upper end thereof, on the rotation of the spindle blade a continuous film of lubricant will be urged upwardly by the rotation and vibration of the spindle blade aided by the capillary action and surface tension of the lubricant. We believe we are the first to provide a structure in which both the vibration and rotation of the spindle blade and the capillary action and surface tension of the lubricant will cause a. continuous lm of lubricant to be urged upwardly between the outer bolster 9 and bolster case 'I to form a continuous radial-cushion for the radial upper ball bearing I0 and to continuously ooze inwardly over the upper end of said outer bolster 9 and downwardly within said bolsters to lubricate said bearing and spindle blade. When the clearance is too great, however, the upward travel common to all spindles, is so violently hammered in intermittentA spouts that it is carried over the bolster case 9. Prior to our invention, it has been impossible to make a single bolster which will accomplish this result as larger clearances are required to cushion the oscillatory movements of the lower end of the spindle blade. Employing our invention, however, the outer bolster is spaced from the bolster case the above amounts to insure the feeding of a continuous lm of lubricant upwardly therethrough and the required clearances for providing oil cushions of suillcient areas are provided between the bolsters themselves to absorb substantially all of the oscillatory high speed vibrations of said spindle blade, thus with a typical load we have provided a .010 inch clearance between the outer bolster 9 and the inner bolster I8 in the medium size textile spindle shown. While this may in the construction shown in Fig. 2 provide intermittent spouts of lubricant between the upper end of the inner bolster I8 and the outer bolster 9, these do no harm as they are immediately deflected downwardly by the ball bearing III and aid in lubricating the radial thrust ball bearing and spindle.` We preferably, however, design the of the oil, which is .type of such spindle.

spindle in every case possible to have the same clearance between the inner. bolster and outer bolsteras to also feed a continuous film of oil upwardly between the inner bolster and outer bolster to lcontinuously ooze inwardly over the upper end of the inner bolster, or bolsters, and downwardly thereof into the oil reservoir located centrally thereof around the lower end of the spindle blade. As stated hitherto, our improved construction permits of high speed rotation of a .flexibly cushioned vertically mounted type of spindle blade carrying proportionately heavy unbalanced loads from 6,000 R. P. M. up to 20,000 R. P. M., a feature not possible in any known It has been found in practice in the prior art that such a medium size textile spindle suitable for approximately three pound bobbins reaches a maximum limit, normally between 6,500 to 7,000 R. P. M., often called the critical speed in the trade to which it may be driven and prior to our invention no such a spindle has been provided capable of being .'driven at a greater speed than said critical unless with a perfectly balanced bobbin. Apparently at around this critical R. P. M. a substantial shift in the position of the axis of rotation of the rotating spindle blade and bobbin takes place and prior art structures have been incapable of accomplishing this shift. Employing our invention, however, it is possible to observe the shift at the axis of rotation as the rotating spindle blade increases in speed which shift, however, is hardly noticeable and in no manner interferes with the operation of the spindle. This shift is usually accompanied with a slight noise and a gyratory movement of the spindle blade. In attempting to force prior art spindle blades through this so-called critical R. P. M., the entire spindle blade vibrates excessively accompanied by much noise, and it has been almost impossible to drive them through the critical speed to the higher speeds desired. We have observed, however, that even if the spindle blade is stationary, if a proper clearance is provided between the respective inner and outer bolsters and the outer bolster and case throughout the height thereof, thin annular bodies of lubricant will rise respectively in said respective places substantially to the tops of the respective holsters by the capillary action and surface tension of the oil alone but the surface tension is so great that the films will not ooze inwardly over the respective upper ends of the bolsters. If, however, the spindle blade be suitably rotated, this surface tension will be broken to permit a continuous circulationA of lubricant radially inwardly over the tops of the respective bolsters, and we therefore, preferably provide such a respective clearance between the respective bolster means and outer bolster and bolster case throughout the height thereof for the more ready circulation of oil in the manner explained, and we have found by experience that if these clearances be maintained, that cushioning bodies of lubricant will be provided of substantial thickness to cushion the aforementioned sets of vibration. These films are formed and circulation of the lubricant is effected during the rapid rotation, ten to fifteen thousand revolutions per minute, and by a capillary action between the holsters urged on by the ne vibration of the high speed which causes the lubricant to travel upward around the outside very slowly and to ow down through the center of the spindle around the blade, to within the hole I5a to also form a cushioning lower end of said spindle blade.

holes 9a and I8a are formedrespectively in the oil lm I6a between the wall of said hole and the Suitable oil respective bolsters 9 and I8 to carry oil from said oil lm I6a formed in the hole I5EL radially outwards through said bolsters so that therespective oil films may be fed upwards as aforesaid between the outer bolster and case by said aforesaid capillary action between the bolsters, urged on by the fine vibration and high speed oscillation of the spindle blade which causesthe lubricant to travel upwards very slowly between the bolster means and the outer bolster means and case to ooze radially over the respective tops of the bolster means and to flow down through the cent-er of the spindle arounde the blade into the reservoir I6a formed in said step I5 between the lower end of the spindle blade II and wall of said step bearing hole I5?.

The primary vibration is set up bythe blade. This primary vibration is accompanied by secondary and tertiary vibrations which must be cushioned to prevent hammering of the spindle and distortion of the blade to provide for smooth and even rotation especially where a heavy load is carried at the top of the blade under the very rapid rotation above mentioned. Thus in general the primary vibrations in a spindle are those caused by faults in the spindle itself including the blade and whirl and are absorbed by the looseness of the blade set in the step bearing in the expansible oil lm surrounding the blade at this point; the secondary vibrations are caused by faulty bobbins and poor fit of bobbin on spindle blade, which quite often give a different set of vibrations, often in different frequency or nonharmonic with the primary vibrations and the tertiary vibrations may be classed as those caused by mis-alignments due to uneven and faulty loading of the bobbin, which usually are of a different frequency and non-harmonic with the primary and secondary vibrations.

However, it usually happens with a large loaded bobbin that at least three different sets of harmonic or non-harmonic vibrations of different frequency are usually present during the rotation of the spindle blade. As stated, the primary set of vibrations may be absorbed between the blade and step bearing, the secondary set between the inner and outer bolsters and the third or tertiary set of such vibrations may be absorbed between the outer bolster and bolster casing.

If a larger plurality of different sets of vibrations be produced, it is obvious that successive sets of oil i'llms to cushion these different sets of vibrations may be provided by providing a greater plurality of closely nested, variably separable or spaceabl-e bolsters.

In actual practice, wevhave found that spindles constructed in accordance with the present invention successfully operate for long periods of time under the condition mentioned, because the several vibrations are cushioned and adequately taken care of by the relative movements between the blade, inner and outer bolsters and between the outer bolster and case. It is essential to provide for cushioning the increased load on a large bobbin to deaden gyratory action, and the provision of means to cushion the vibrations is an essential feature in this connection. When these types of vibrations, which vary according to the load and speed of rotation, are absorbed around the lower portion of the spindle the gyratory or oscillating action of the bobbin is cushioned'v and smooth and quiet operation with long life to the spindle and bobbin is provided.

Fig. 3 shows a modification of the invention in which the casing 1' is provided in its lower end with seat 22, for the outer bolster 23, loosely mounted within the casing 1', and provided at its upper end with an enlarged head 24. The head 24 has a shoulder 25 confronting the annular ledge 26 within the casing 1'. The head 24 is provided with an annular groove 21, and also carries a key 28, which fits in longitudinal groove 29 of the casing to prevent relative rotation between the bolster 23 and the casing. The head 24 of bolster 23, is also provided with a groove 3D, which receives key 3| of the inner bolster 32 to prevent relative rotation between the respective bolsters. The upper end of the bolster 32, is also provided with a head 33, having an annular groove 43, substantially in alignment with the groove 21 when the parts are completely assembled.

In the embodiment of the invention being described the movable bolsters are' supported by their shoulders or bases.

Blade 35, is driven by usual whirl 36, and the inner surface of the head 33, of the bolster 32, forms a journal for the portion 38, of the blade. The lower part of the blade 35, tapers gradually inwardly and downwardly within the bolster 32, providing a gradually increasing space 39, between the bolster 32 and the blade 35. The lower pointed end 4|! of the blade 35 is shown seated on a bearing surface 4| of the bolster 32. The lower end of the bolster 32 is pivotally supported on seat 42 of bolster 23. The bolster 23 is separated from the casing 1 by tapering space 43, and the bolster 32 is similarly spaced from the bolster 23, as indicated at 44. This provides for relative movements between the respective bolsters and between the bolster 43 and casing 1 for the purpose of balancing the load on the upper end of the blade 35 as explained in connection with Fig. 2, by absorption of the vibrations created during the rotation of the bobbin and the building-up of the load thereon.`

The lubricant is fed through passage 45 to the opening 46 in bolster 23 to space 44 between the s scribed. In Fig. 4 the numeral 58 designates the casing within which are mounted the bolsters and blade. Bolster 5| is shown seated on its lower end on the seat 52 of the casing 50, and arranged` loosely within the casing for lateral movements relative thereto. Whereas, in the embodiments of the invention hereinbefore described the outer bolster, extended substantially to the upper'end of the casing, in the present embodiment of the invention the upper end of the bolster 5| terminates substantially in alignment with the rail on which the spindle is mounted, as designated by the numeral 53. The inner bolster 54 is provided with a step or bearing 55, which supports the lower end 56 of the blade 51. The lower end of the inner bolster 54 rests ona seat 58 at the bottom of bolster 5|; the arrangement being generally similar to that provided for the corresponding parts in Fig. 3.

The inner bolster 54 extends above the outer bolster in the construction of Fig.4, and is provided with an enlarged head or end 59, which is located in a chamber 68, defined by the walls 6| on the upper end of the casing or support 58. The vhead 59 is provided with amiamber s2 in which is mounted a ball bearing 63 as shown also in Fig. 2.

As in the other embodiments of the invention the blade designated by numeral 51 is rotated by whirl 84. The head 59 of the inner bolster is provided with an annular groove 65, to acilitate lubrication. Key 66 engages a longitudinal groove 61 in the Wall 6| of the casing to preventrelative rotation between the inner bolster and casing.

The interior of the bolster 1|) decreases in diameter from top to bottom as defined by the ledges or shoulders 68. The blade 51 is tapered from top to bottom and is provided adjacent its bottom with a shoulder 89.

holsters. The'bolster 32 has an opening 41, to

supply lubricant to the bearing 4|, and the lower end of the bolster 23 has an opening 48 to supply the lubricant to the space 43. The lubricant openings may be varied in number and relative location as desired.

When the lubricant circulates throughout the inner structure in the manner previously described, that is by upward ilow between the respective inner and outer bolsters and outer bolster and bolster case, inward radial flow over the respective tops of the bolsters and downward ow, over the upper bearing and spindle blade into the well I6a and radial outward flow through the respective passages 41 and 48 to the respective spaces between the inner and outer bolsters .and outer bolster case, the spaces between the relatively movable parts are filled with bodies of lubricant which cushion the parts to absorb the vibrations, (primary, secondary and tertiary), providing smooth operation, and preventing hammering between the blades and bobbins even when the weight of the thread spun or wound on the bobbins is relatively large and varies throughout the spinning operation.

Fig. 4 shows a further modification of the invention which, however, embodies the essential general principles before, mentioned vand de- Preferably tapering spaces 1|, one between the casing 50 and the bolster 5|, and another 12 between che inner bolster portion sa and the our bolster 5|, are provided to receive oil or other lubricant to eiect the cushioning previously described, under the conditions specied. The lubricant is fed through passage 13 to the spaces 1| and 12, and the openings for passage of the lubricant may vary in number and relative locaion.

The construction of Fig. 4 accomplishes the same results as to absorption of vibrations as the embodiments of the invention above described, as it avoids the hammering eilect of the blade both within the bobbins and Within the mountings. This is due principally to the loose t of the blade within the inner bolster, the loose t of the inner bolster within theouter bolster, and the loose t of the outer bolster within the casing, with due provision for cushioning by the oil lms according to the varying conditions created during the spinning operation, and radial outward iiow through the respective passages 41 and 48 to the respective spaces Abetween the inner and outer bolster and outer bolster and bolster case for the same continuous cycle of recirculation as `previously pointed out for the other embodition of Figs. 3 and 4. In Fig. 5, the inner bolsterv terminates adjacent the vplane of the supporting rail and the outer bolster extends thereabove and is provided with an enlarged head chambered to receive a roller bearing. The numeral 50' designates the casing or fixed support for the movable parts of the spindle. The casing 50' is provided with an extension 15 having a passage 16 through which the lubricant is supplied. This is standard structure and may be used in connection with any of the embodiments hereinbefore described. A hinged cap 11 closes the inlet end of t-he passage 16. A lever or knee brake 18, of known construction and operation, is provided to clamp the whirl and stop rotation of the spindle when desired.

The outer bolster 19 is provided on its lower end with a seat 80 for the inner bolster 8|. The inner bolster has secured within its lower end as by a pin 82, a plug which serves as a bearing surface for the end 84 of the blade 85,` similar in construction to the blade 51 of Fig. 4. It will also be noted without further detailed descriptio'n that the interior of the inner bolster 8| is formed to accommodate the stepped or tapered construction of the blade 85.

As previously mentioned, in connection with the construction of Fig. 5, the upper end of the bolster 19 is provided with an enlarged chambered head which is designated by the numeral 85, and the inner bolster 81 is provided with an annular flange 88 which fits within the chamber 09 of the head 88. The flange or head 88 is provided with an opening or openings 90 to permit the circulation of oil inV accordance with the principles of the invention relating to method of lubrication. The head 88 of the inner bolster is keyed to the enlarged head 86 of the outer bolster 19 as by means of a pin 9| to prevent relative rotation therebetween. The outer bolster is maintained against rotation relative to the casing 50 as by means of a key 92 which engagesl in a longitudinal groove 93 in the wall 94 on the upper end of the casing support.V The blade 85 may be rotated in known manner by a whirl 95, and the antifriction bearing 96 may be provided for the purposes described in the aforesaid prior patent and for cooperation with the other features above described and pointed out for properly maintaining the axis of rotation of the blade and bobbin thereon in true vertical alignment within such close limitations as will prevent hammering and gyratory or oscillating movements between the bearing and the load, which oscillations or vibration when not absorbed normally result in destruction of the blade, the bolsters or bobbin. When proper balance is maintained, in the manner specified, the blades, the bolsters and bobbins will not hammer injany marked degree even when large bobbins are carried on the blades. It is obvious that in this embodiment also the continuous circulation of oil will take place in the manner hitherto described.

It should be noted from the foregoing that the possible variation, combinations, and permutations, in the present invention to accomplish the attainment of the stated objects and advantages, are practically unlimited as to details. For instance in Fig. 2, two loosely mounted inner and outer bolsters are supported on the bottom of the casing, and the step of the inner bolster supports the blade at its bottom end to carry the load. In Fig. 3 both inner and outer bolsters extend substantially to the top of the casing with the bolsters shouldered adjacent the top of the ing; whereas in Fig. 5 the construction of Fig. 4

is reversed so that the outer bolster extends above the inner bolster and is provided with a chambered head supporting a self-aligning ball bearing. Thus the fulcrums for oscillating movements of the bolsters and blades may be varied.

It is obvious that vif desired, as shown in said prior Patent #1,511,257, the plug I5 may be removed to permit the continuous circulation of oil rst axially downwardly through the lower end of the hole I5n and that the spindle may be constructed below the step in the manner shown in said patent to permit the oil to then circulate radially outwardly to be fed upwardly as said respective cushioning oil films in the spaces between the inner and outer bolsters and outer bolster and case in the manner previously explained. We have shown such a construction in Figs. 6-9 which is similar to the construction shown in Fig. 2 herein, modified in accordance with the teachings of said prior Beede Patent No. 1,511,257, with the plug I5' thereof removed to permit the continuous circulation of oil, rst axially downwardly through the lower end of the hole |53 as indicated by the arrows U and then radially outwardly as indicated by V underneath the innermost bolster I8 to be fed upwardly at modulated speed as indicated by the oil lm and arrows W between the innermost bolster I8' and outer bolster 9. We have shown in Figs. 6-9 the embodiment of means for non-rotatably securing the lower end of a spindle bolster, such as the outer bolster 9 to the lower end of its bolster casing shown in the copending application of Herbert G. Beede, one of the joint members herein, S. N. 209,470, Means for non-rotatably securing the lower end of a spindle bolster to the lower end of itsv bolster case, filed May 23, 1 938, in which the ngers |00 project upwardly from the base plug |02 into a plurality of complementary slots |04 in the lower end .of the outer bolster I8 of greater length than said fingers |02 to provide the radial oil circulation openings |06 in the lower end of said bolster means I8' between the ends of said ngers |00 and slots |04. It is thus obvious that a portion of the oil stream fed upwardly as atW will be circulated radially outwardly through said holes |06 to be fed radially upwardly as 'indicated by the lms and the arrows X between the outermost bolster I8 and bolster case 1. It will be noted that the respective outermost bolster 9 is spaced so closely from its inner bolster I8 and bolster case 1' respectively with the clearances mentioned above throughout the height thereof as to permit continuous films of lubricant as indicated by the respective arrows W and X to be urged upwardly by the capillary action of the lubricant between said respective bolsters 9 and I8 and outer bolster 9 and bolster case 1' as continuous lms to be forced to ooze inwardly on rotation of the spindle blade over the upper ends of the respective bolster means, as indicated by the arrows Y over the upper end of the outer bolster means 9 and by the arrows Z over the upper end of the innermost bolster means I8' by rotation of the spindle blade to flow downwardly as indicated by the arrows T over the bearing I0 to lubricate said respective bearings I0 and l5 and spindle blade It is apparent, however, that if either bolster means be only so closely spaced with the proper clearance from the other bolster means or the bolster case yfor a substantial distance adjacent the upper end thereof, that a modulated flow will still be produced between the upper ends of said members even if a churning action takes place between the lower portions of the respective members spaced apart a greater distance than said respective clearance distance.

While our invention is especially adapted for use on spindles adapted to carry bobbins for spinning or twisting yarn or thread, it is apparentthat it may be employed on any type of a rotatable spindle for any other use such as in extractors.'

In all embodiments of the invention the result is substantially the same as to accomplishment of the objects of the invention hereinafter stated, and we have shown the several embodiments in this application purely as illustrative and representing preferred forms at the present time.
